Application filed April 23, 1910. Serial No. 557,195. I

To all whom it may concern:

Be it known that I, MARTIN JAMES Gun- 'l'lS, a citizen of the UnitedStates, residing at Billings, in the county of Yellowstone and State ofMontana, have invented certain rangement of parts forming the generatingvessel and novel means for supporting a lamp thereon.

A st1lL further object is to provide means for supporting the lamp uponthe cap or the user.

Other objects and advantages will be apparent from the followingdescription, and

it will be understood that changes in the specific structure shown anddescribed may be made within the scope of the claims with out departingfrom the spirit of the invention.

In the drawings, Figure l is a side elevation of my improved lamp, inposit-ion for use, Fig. 2 is a vertical central sectional View taken onthe line 3-3 of Fig. 3, Fig. 3 is a top plan view of the device, Fig. 4eis a detail view of the supporting bracket for the burner globe, Fig. 5is a detail view of a retaining member for the top of the globe.

Referring to the drawings in which like characters denote like parts, 1have shown my improved miners lamp, which comprises the carbid reservoir10, which as more particularly shown in Fig. 2 of the drawings I has aconcaved inner face ada ted to con form tothe shape of the cap Q thewearer, the outer and side faces of the reservoir being angular in crosssection, said reservoir having attached to, its concaved inner surface,a depending pin. 11 adapted for securing the device tothe cap in theusual manner. The reservoir is adapted to contain the.

carbid in granular form and is provided with a screw cap 12, through themed um of which the carbid is fed to the reservoir.

Disposed upon the upper wall of the reservoir and depending into anopening'therein is a water tank 13, which is supported upon the upperwall of the reservoir as by means of an annular flanged ring 14, whichis secured to the tank and the reservoir and. said tank is also providedwith a screw cap l5 through which water may be poured into the tank. Thelower end of the tank 13 is slightly conical and has an extension 16 ofreduced diameter and having a central bore 17 and a conical valve seat18,-said bore being opened or closed as desired by means of an operatingstem 19 having a corresponding"conical end adapted to be received in theseat 18 and thereby regulate the amount of water discharged from thewater tank.

The stem 19 extends through the outer wall of the reservoir and isprovidedv with an operating head 20. i

Extending outwardly from the outer wall of the reservoir there is asuitable bracket 21 having a suitable angular brace member 22 securedthereto, the outer end of said bracket being adapted to support acylindrical base 23, said jacket having a central aperture 24' throughwhich a burner pipe25 is extended, said pipe being in communication withthe reservoir above the operating stein 19 and extending at an angle tobeneath said cylindrical base and more especially the aperturetherethrough. The burner pipe is adapted to convey the gas generatedwithin the reservoir to the burner and a valve 26 of the usual type isprovided for regulating the flow-thereof, it being understood that thecarbid is poured into the reservoir through the opening therein and thewater tank similarly filled with water,

the valve stem is then operated to allow. the

water to drip very slowly from the tank so a proper amount of gas willbe generated and flow through the burner pipe, for all useful purposes.

Supported upon the cylindrical base 23 is a burner globe 27, which ispreferably of glass and adapted to be positioned at a slight distancefrom the reservoir, the burner being adapted to extend upwardly a slightdistance within the globe. To prevent the globe from becoming displacedupon the cylindrical base 23 I provide a spring keeper which comprisesan arm 28, which is secured to the upper end of the water tank, theouter end of said arm being bent to form a de- I pair of cross arms 30having depending ends match or the like may be inserted underneath theglobe.

- From the foregoing it will be seen that I have provided a miners lampwhich can be very cheaply manufactured and one which will be verydesirable for such use, inasmuch as there is small liability of the samecatching fire, thereby avoiding accidents usually occurrin from thiscause.

What is claimed is:

1. A miners lamp comprising a gas supply reservoir, a bracket securedadj acent the bottom of the front wall of the reservoir. and having apair of openingstherethrough, a burner pipe extending from thereservoir, said pipe being disposed downwardly through one of saidopenings and upwardly through the other of said openings, a burnercarried thereby, a globe supported upon said bracket and a keepersecured to the top of the reservoir and engaged with the upper end oftheglobe to hold the same in position.

2. A miners lamp comprising a suitable gas generating vessel, havingmeans for securing the'same to the cap of the user, a

' supporting bracket secured to the vessel and extending outwardlytherefrom, said bracket havmg a circular base upon its outer endprovided with an annular groove, a valve controlled burner carryin pi ein communication with the vesse m extending throu h the base, a globehaving an enlarge upper portion and a restricted lonier end seated insaid roove, and means bracing the globe at its upper end.

3. A lamp comprising a suitable generatfor - ing vessel for gas,saidvessel having a concaved inner surface, means secured to saidsurface for attaching the same to an object a bracket secured to thelower front wall of said vessel, a cylindrical base carried by saidbracket, said base having a central aperture therethrough, a burner pipeextendingfrom said vessel and adapted to convey gas therefrom, saidburner pipe extending u wardly through said aperture and provide with asuitable burner, a valve in said pipe for regulating the supply of as, aglobe supported upon said base an over the burner and a spring keepersecured to said generat-
